Checking The Chain Tension; Checking The Machine; Checking The Chain Brake - Stiga SPR 255 Manual De Instrucciones

PREPARING TO WORK
– Never remove the fuel tank cap or add fuel
while the engine is running or still hot.
– Check for any leaks.
– Start the engine well away from the refuel­
ling point.
Before refuelling:
– Shake the fuel mixture container well.
– Place the machine on a flat stable surface, with
the fuel tank cap facing upwards.
– Clean the fuel tank cap and the surrounding
area to avoid any dirt from entering the tank
during refilling.
– Carefully open the fuel tank cap to allow the
pressure inside to decrease gradually. Use a
funnel to refill and avoid filling the tank to the
brim.
WARNING!
cap firmly.
WARNING!
ces of fuel which may have dripped on the
machine or the ground and do not start the
engine until the petrol fumes have dissipated.
3. CHAIN LUBRICANT
IMPORTANT
saws or adhesive oil for chain saws. Do not use oil
containing impurities so as not to block the oil filter
and to prevent irreparable damage to the oil pump.
IMPORTANT
the chain is biodegradable. Use of a mineral oil or
engine oil causes serious damage to the environ­
ment.
It is essential that you use good quality oil to lu-
bricate the cutting parts effectively. Used or poor
quality oil does not guarantee good lubrication and
reduces the duration of the chain and bar.
It is always worth topping up the oil tank complete ly
(using a funnel) every time you refuel. Since the oil
tank capacity is enough to guarantee that the fuel
runs out first, you will avoid the risk of operating the
machine without lubricant.

4. CHECKING THE MACHINE

Before starting work please:
– check that the clutch functions properly (chain
does not move in idle)
– inspect the chain-saw daily or before using, or
after being dropped to identify significant dam-
age or defects,
– fill the relevant tanks with fuel and oil;
Always close the fuel tank
Immediately clean all tra-
Only use special oil for chain
The special oil for lubricating
– check that all the screws on the machine and the
bar are tightly fastened;
– check that the chain is sharp and there are no
signs of any damage;
– check that the air filter is clean;
– check that handgrips and protection devices
are clean and dry, correctly mounted and well
fastened to the machine;
– check that the handgrips are well fastened;
– check that the chain brake is working efficiently;
– check the chain tension.

5. CHECKING THE CHAIN TENSION

WARNING!
with the engine off.
The tension is correct when the drive links do not
slip out of the chain guides if you hold the chain in
the middle of the bar (Fig. 7).
– Loosen the cover nut, using the supplied wrench
(Fig. 5).
– Turn the chain tension adjuster screw (4) to ad-
just the chain tension (Fig. 5).
– Lifting the bar, tighten the cover nut securely
using the supplied wrench (Fig. 6).

6. CHECKING THE CHAIN BRAKE

This machine is equipped with a safety brake sy-
stem.
The chain brake is a device which stops the chain
instantaneously if the chain saw recoils due to
kickback. Normally, the brake is activated auto-
matically by i nertial force. It can also be activated
manually by pushing the brake lever (left-hand
guard) down toward the front.
This brake can be operated manually by pushing
the front guard forward. To release the brake, pull
the front guard towards the handgrip until you hear
a click.
To check that the brake works efficiently, proceed
as follows:
– Make sure you are holding the machine firmly
with both hands when you start the engine
– Use the accelerator level to keep the chain
moving, push the brake lever forwards using the
back of you left hand; the chain must stop im-
mediately.
– When the chain has stopped, immediately re-
lease the accelerator lever.
– Release the brake.
WARNING!
the chain brake does not function correctly
and have it inspected by your dealer.
